      <title>Overview</title>
      <p>
	We've all heard the buzz about this AJAX thing, and over and over there are questions asked on the
	Struts mailing lists about how to use AJAX in a Struts app.  Well, now you have what is, hopefully, a
	good real-world example of doing just that!  This is your typical chat application ala Yahoo! Chat,
	built on Struts and utilizing AJAX techniques.  It is hoped that this shows how to meld the two
	together to produce applications that might not otherwise be possible.

        <title>Usage</title>
         <p>
         At present, AjaxChat is available in a zip archive that is an exploded webapp.  Simply unzip it into the appropriate
         location in your servlet container of choice and you should be all set.  It *may* be necessary to also add the
         Commons Validator to WEB-INF/lib in some containers.  This will be rectified in a future release.

          Wendy Smoak has helped test this on occassion, so I suppose you could call her a contributor!
